Abstract

Disclosed is a kitebar, in which an additional handle is provided for moving, which simplifies the trimming at the start course.

Description

The invention relates to a kitebar according to the preamble of patent claim 1.

Conventional five-liner and four-liner bars usually have two control lines acting on the tips of the kite and two front lines running in a V-shape. The latter are connected via an adjuster with one or two depower lines, which are led through the bar to a chicken loop. About the Adjuster the effective length of the front lines and thus the angle of attack of the kite to the wind can be adjusted.

Such Kitebars are for example in the DE 20 2010 013 802 U1 , of the DE 20 2011 050 475 U1 , of the DE 20 2012 100 690 U1 and the DE 20 2012 101 875 U1 described.

In the US 2002/0 084 384 A1 is a Vierleinerbar described in which the front lines and the control lines are adjustable via a winding mechanism which is mounted on a parallel to the bar extending axis.

To depower the kite, the bar is pushed away from the surfer towards the adjuster so that the angle of attack of the kite is reduced to the wind. To power on, the bar is pulled towards the surfer (away from the adjuster) so that the angle of attack increases accordingly. The basic setting of the kite is u. a. over the adjuster, which determines the angle of attack of the kite in a basic position of the bar. The maximum depower path when moving the bar along the depower lines can be limited by a bar stopper, which is set adjustable on the depower lines.

Triangular regattas use so-called race boards, which are designed as unidirectional and have Finns with a comparatively large lateral surface to improve the air-resistance properties. Unlike the Bidirectionals (twintips), the race boards are held flat on the water during run-down, so as not to reduce the effective fin area. It is necessary for the surfer to lean far out to the windward to bring the kite's forces to the board. Here, the upper body is still rotated in the direction of travel, so that it is quite difficult for the surfer to take advantage of the entire Depowerweg the bar, without giving them a maximum Amwindgeschwindigkeit guaranteeing position.

The maximum wind speed is achieved when the kite is set as flat as possible so that it provides minimal wind resistance. However, this assumes that the bar is moved as far as possible towards the barstopper. However, the displacement is significantly lower in the upwind position due to the described posture of the surfer than in the case in which the surfer stands upright on the board.

In contrast, the present invention seeks to provide a kitebar, which allows a higher air flow speed.

This object is achieved by a kite bar having the features of patent claim 1.

Advantageous developments of the invention are the subject of the dependent claims.

According to the kitebar has a bar, at the bar ends each a control line attacks and in the central area has a guide for at least one depower line along which the bar for trimming the kite is displaceable. This depower line is connected on the one hand via an adjustable adjuster with two branching front lines and on the other hand with a chicken loop.

According to the kitebar is designed with an additional handle, which is in operative connection with the bar and the distance to the Adjuster or a barstopper is greater than the distance between the bar and the barstopper / Adjuster.

The surfer, it is thus possible to take when blowing on the closer to him arranged handle and thus to move the actual bar on the handle in the direction of the adjuster to trim the kite as flat as possible. The additional displacement corresponds in principle to the distance of the handle from the conventional bar.

From the US 5,366,182 A Although a bar with two bar bars is known. However, this bar is used for a two-liner, increasing the depower path by moving the bar position is not possible and not intended.

In a particularly preferred embodiment of the invention, the handle is connected to the bar.

This connection can for example be a rigid connection or else articulated, so that the handle is pivotally mounted on the bar.

This makes it possible to pivot the handle from an operative position to a rest position, in which the distance of the handle to the adjuster / barstopper is reduced. That is, the handle can, for example, in half-wind or Raumschots- Driving away can be panned so that the surfer can once again grab the actual bar in a conventional manner. In these courses, a significantly more upright riding position of the surfer on the board is possible, so that even without the handle of the maximum Depowerweg is exploitable.

This pivoting can take place, for example, about the bar axis or an axis arranged parallel to the bar, so that the handle can be pivoted through approximately 180 °.

In a preferred embodiment of the invention, the handle is approximately U-shaped, wherein the two U-legs / end portions of the handle are fixed or hinged to the bar.

In order to avoid a collision of the handle with the chicken-loop or the surfer, the handle can be designed with a concavity, so that it does not or only slightly comes into contact with the chicken-loop and remains at a distance to the surfer.

In such an embodiment, the grip areas can then be executed on both sides of the concavity.

The handle can be made tubular like the bar itself. In principle, it is also possible to form the handle in several parts or of an elastic material which in principle is so tensile and sliding resistant that the required holding forces can be applied.

The kitebar is preferably designed with two depower lines that pass through a center piece of the bar.

To minimize the friction, however, it may be advantageous if the handle is not penetrated by the depower lines or.

A preferred embodiment of the invention will be explained in more detail below with reference to schematic drawings. Show it:

1 a three-dimensional partial representation of a Kitebar invention;

2 the Kitebar 1 with a pivoted handle and

3 the Kitebar 2 in a position for flattening the kite.

1 shows a three-dimensional representation of a part of a kitebar 1 , This has a plastic coated bar 2 , at their barends 4 . 6 Lanyards are arranged in 1 not shown, as they each come from a floater 8th . 10 are covered. On this lanyards can be two control lines 12 . 14 be attached, which attack on the tips of the kite (not shown). These steering lines 12 . 14 are also called back lines. The bar 2 has one through an insert 16 formed implementation, through which in the illustrated embodiment, two depower lines 18 . 20 extend. Their end section, which is remote from the kite, has a chicken loop 22 connected. The structure of such a chicken loop is for example in the DE 10 2009 029 987 A1 disclosed by the applicant, so that further explanations are unnecessary.

The other end portion of the two depower lines is with an adjuster 24 connected, which is designed according to the flat pulley principle and over which the angle of attack of the kite is adjustable. The loose end of the adjuster is in a pinch 26 fixable. The surfer can see the end section 28 Grasp the adjuster line and release it from the clamp, and then change the pitch of the adjuster to set the desired base trim. On the two depower lines 18 . 20 is a barstopper 49 guided, the maximum displacement of the bar 2 limited. This barstopper 49 can be at the desired position on the depower lines 18 . 20 be determined. Possible constructions of this Barstoppers are mentioned in the beginning DE 20 2012 100 690 U1 described.

The adjuster has a pulley 30 , at the two V-shaped front lines 32 . 34 attack. Alternatively, these front lines 32 . 34 be carried out with a common central line, which is then attached to the deflection roller or on the adjuster. The front lines 32 . 34 engage the front tube of the kite, so by adjusting the adjuster 24 , as explained above, the angle of the kite is independent of the bar position adjustable.

Up to here, the structure of the bar corresponds 2 that of conventional solutions.

The peculiarity of in 1 illustrated bar 2 exists in the handle 36 at the bar 2 is fixed and the dargstellten embodiment by 180 ° from the illustrated rest position in the in 2 shown active position is pivotable. The pivoting takes place about a pivot axis 38 which coincides with the bar axis or is arranged parallel thereto.

In the illustrated embodiment, the handle has 36 an approximately U- or W-shaped structure with two short side legs 40 . 42 who are articulate at the barends 4 . 6 are stored. These are the two end sections 44 . 46 the thigh 40 . 42 inflected towards the bar axis. The two side legs 40 . 42 are about a base 48 connected with each other. This has an approximately centrally located concavity 50 whose function will be explained in more detail below. Side of the vault 50 two gripping areas remain 52 . 54 where the kiter handles the handle 36 grasps.

In the in 1 illustrated position of the handle 36 The surfer takes the bar 2 - He is usually on a space or semi-wind course or the wind is relatively weak, so that he does not "fully" on the start course and the kite remains powered up.

In the case in which the kiter is "leaning out" to the windward when blowing on it becomes the handle 36 from the in 1 illustrated rest position by 180 ° in the in 2 adjusted active position adjusted. In this is the distance A of the handle 36 from the barstopper 50 significantly larger than the distance a of the bar 2 , That is, the difference A - a corresponds to the same posture of the surfer an additional trim way to which he can move the bar up in the direction of depower. However, it is assumed that the length of Depowerleinen 18 . 20 allows this displacement. Such a long Depowerweg is in a tough upwind course at top speed with direct attack on the bar 2 and optimal weight trim not possible - the surfer is thus able to handle the handle 36 make the kite flatter and thus achieve a higher driving speed with optimum weight trim. 2 shows the bar 2 or the handle 36 still in almost fully powered condition. One recognizes that the vaulting 50 ensures that the handle 36 not too close to the body of the surfer or to the chicken-loop 22 comes close, causing an accidental triggering of the chicken loop 22 or obstruction of the surfer is avoided.

To flatten the kite is then according to 3 the handle 36 in the direction of the arrow away from the surfer towards the barstopper 49 shifted, with the maximum displacement by accumulating the bar 2 on the barstopper 49 is limited.

At the maximum displacement, that is, when the bar 2 at the bar stopper 49 could the bar 2 no longer be easily reached by the surfer as the handle 36 However, if it is located much closer to it, it can easily adjust this trim position of the kite.

In the illustrated embodiment, the handle 36 formed approximately tubular and is preferably also provided with a foam sheath to improve the grip. Of course, other constructions for the handle 36 executable. So this can be made of an elastic material over which only the required for trimming shear and tensile stiffness is provided. The handle can be rigid with the bar 2 be connected. In principle, it is not necessary, the handle 36 to pivot in the manner shown, but there are also other pivoting directions conceivable. In principle it is also possible to carry out the handle in several parts, so that, for example, a separate handle is provided for each hand, which is brought into the operative position by pivoting, twisting, folding or other way. The handle can also pocket knife-like from the bar 2 be swung out.

Disclosed is a kitebar, in which an additional handle is provided for moving, which simplifies the trimming at the start course.
